Network problems

[gregoire]

Hello,

I have had a pogoplug running arch linux for a few month now without problems until I had to restart it yesterday. Now it won't boot properly. I don't really know what is going on, the only clue I have is that every few seconds, the network seems to be going on and off and there is a lot of those in kernel.log:
$this->bbcode_second_pass_code('', '
mv643xx_eth_port mv643xx_eth_port.0: eth0: link up, 100 Mb/s, full duplex, flow control disabled
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
')

If I remove the drive on which arch is installed, the device boots and I can ssh to it. So I tried installing a fresh version on a different usb key, following the procedure there:http://archlinuxarm.org/platforms/armv5/pogoplug-v2-pinkgray (I have a POGO-E02) and I get the same thing.

Since I'm switching ISP I figured that this could be the problem but I don't know what to do to find out what is going on.
Any ideas?

Why would switching ISPs make your network connection go up/down?

If it's the router - then you can assign an ip to the pogoplug, assign an ip to your computer and connect them with a crossover cable - see if it does same thing or just try a different router.

1) it should auto-negotiate, but some routers/switches don't do it nicely.
2) WTF it boots to pogoplug ?
3) Wow, what is that brand of router so I can never use it?

Hey gregoire,

I've been having some network problems too with the series 4 too and I've been trying a few things such as forcing dhcpcd to start up by changing the rc.local file and setting a static ip address. In the end, the static ip did the trick too. Its funny how you mentioned how you had a netgear router because I too connect my pogoplug to a netgear router provided by my ISP. I'm not too convinced either that its the router's fault because I had arch booting on the same router and same device before. The problem arise after installing a fresh copy of the most recent rootfs. I have another router in my network (A linksys one) and I connected the pogoplug to it and still no luck with ssh-ing into the pogoplug using dhcpcd.
